ERNEST C. FORD, OF FITGHBURG, MASSACHUSETTS.

HAND-PROTECTOR FOR SPRAYING DEVICES.

To all whom it may concern Be it known that I, ERNEST C. Form, a citizen of the United States, residing at Fitchburg, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Hand- Protectors for Spraying Devices, of which the following is a specification.

My invention relates to spraying devices, and more particularly to an attachment forming a shield for the hand of the operator.

My object is to provide means for preventing the spraying fluids from running down from the nozzle onto the hand of the operator, since these fluids, being intended to kill insects, are often poisonous and otherwise objectionable.

Another object is to so construct the device that it will also protect not only the hand of the operator, but also the adjacent portion of the arm as well, from the drops of spraying fluid which fall from the foliage while it is being applied.

A third object is to provide a device which can be readily attached to any nozzle, whatever its size, and which can as easily be detached therefrom.

Other objects will appear in the subjoined description.

The invention consists in certain novel parts and combinations of parts, as will be hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of my device in operative position on the nozzle of a spraying hose. Fig. 2 is a top plan view of one form of the device. Fig. 3 is a top plan view of a modified form. Fig. 4 isa sectional View of the form of the device shown in Fig. 2; and, Fig. 5 is a central, vertical section of still another form.

My device is formed of rubber or any other preferred material, either rigid or yielding.

The numeral 1 indicates the main body portion of my device, which is preferably circular in form, and is provided at its center with a raised or thimble portion 2. At the center of the thimble portion 2 in the top thereof, I provide a small opening 3 adapted to receive the nozzle of the hose to which the device is to be attached. When the device is formed of rubber this hole 3 may be made very small, since the flexibility Specification of Letters Patent.

of the material will permit it to stretch to suit the size of any nozzle with which it may be desired to use the device; or the device may be manufactured and marketed without the hole 3, leaving that to be made by the purchaser, according to the size of the nozzle he may desire to use the device with. When the thimble portion 2 is formed of rigid material, the opening 3 should be adapted to fit the outer periphery of the noz zle with which the device is to be used. This can easily be done when the nozzle and shield are both made by the same manufacturer; in which case also, the opening 3 and the outer periphery of the nozzle may, if desired, be provided with cooperating screw threads. When however my shield is manufactured without a definite knowledge of the exact kind of nozzle with which it is to be used, it is better to form the thimble portion 2 of yielding material.

The inside 3- of the thimble opens at the under side of the body portion 1, and is preferably larger than the nozzle with which the device is to be used.

iVhen the device is formed of rubber or other yielding material, the circular portion 1 is made thicker at the center, and gradually becomes thinner as the periphery is approached, as indicated by the oflsets 4L, 5, and 6.

In Fig. 3, I have shown the body of the device provided at one side with an integral extension 7, having at its outer end two parallel slits 8, adapted to receive a transversely extending buckle strap 9. The extension 7 in this form of the device, is intended to extend out over the wrist and a portionof the arm of the operator to protect them from the falling drops of the spraying fluid. The strap 9 encircles the arm of the operator, but may be made quite long when desired, so that it forms a downwardly-extending loop, thus providing room for easy play of the arm therein.

In Fig. 5 I have shown the central thimble of the device formed of rubber provided on its outer periphery, near its lower end with an annular groove 10, adapted to be engaged by the circular plate 1 which may be formed of metal or other rigid material, and

which is provided at its center with an opening 11, adapted to cooperate wlth the annular groove 10 of the thimble 2, to firmly hold the two together. In this way the thimble 2 can be replaced with a new thimble whenever it becomes seriously damaged by the spraying fluids, or ceases to fit the nozzle satisfactorily.

Of course the thimble portion 2 may be omitted from my device, which in that case would be simply provided at the-center of the circular portion 1, with an opening for the nozzle equivalent to the present opening 3 in the thimble; but the arrangement shown is better, because when the nozzle is passed tightly into the opening 3, the yielding outwardly of the side walls of the thimble 2 prevents the circular portion 1 of the device from buckling, as it otherwise would do, from the radial strain that would be im posed upon it if it were simply a fiat disk or plate with the nozzle inserted through a hole in its center.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is l. A device of the character described having an approximately flat body portion provided at its center with an upwardly extending thimble formed of yielding mate- Oopies of this patent may be obtained for rial, the top of said thimble being provided with an opening adapted to tightly engage a nozzle; the inner diameter of the thimble below said opening being greater than the outer diameter of the nozzle with which the device is designed to be used; whereby the radial strain imposed upon the top of the thimble, when the device is forced upon the nozzle, will not be imparted to the main body of the device to cause the same to buckle.
